perf tools: Add --tui and --stdio to choose the UI

Browse Source 
Relying just on ~/.perfconfig or rebuilding the tool disabling support
for the TUI is too cumbersome, so allow specifying which UI to use and
make the command line switch override whatever is in ~/.perfconfig.

--input=::
Input file name. (default: perf.data)
--stdio:: Use the stdio interface.
--tui:: Use the TUI interface Use of --tui requires a tty, if one is not
present, as when piping to other commands, the stdio interface is
used. This interfaces starts by centering on the line with more
samples, TAB/UNTAB cycles thru the lines with more samples.
